Precision Time Protocol Introduction
At the first boot of a Cisco ISR router, some basic configuration has to be performed to secure adminitrative access to the router. This lab will test your ability to configure the basic security settngs of a Cisco ISR router and help you to get ready for the router configuration simulation activities in the CCENT / ICND1 certification exam (Chapter 5.0 Infrastructure Maintenance of Cisco Certified Entry Networking Technician (CCENT) exam)

Lab instructions
The aim of this lab is to test your ability to perform a basic router setup. You have 15 minutes to complete this simulation.
1. Configure the LAPTOP terminal software with the right console parameters.
2. Configure the router hostname to "GATEWAY"
3. Configure the enable password and secret to "cisco"
4. Configure password encryption on the router to secure stored passwords
5. Configure the console access :
- Login : yes
- Password : "cisco"
- History : 10 commands
- Logging synchronous
- Timeout : 2 minutes 45 seconds.
Solution
1. Configure the laptop terminal software
The terminal software in not correctly configured on the laptop. You have to change the settings to 9600 / 8 / None / 1 to connect to the router's console. Remerber this tip as it could help you answer CCENT questions or achieve CCENT simlet.
2. Configure the router's name
The hostname command has to be used to changethe router's hostname.
Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname GATEWAY
3. Configure the enable password and secret to "cisco"
The enable secret <password> command stores a MD5 hash of the password required for privileged mode access. The enable secret password of a Cisco ISR router is used for restricting access to enable mode and to the global configuration mode (configure terminal) of a router.
GATEWAY(config)#enable secret cisco
4. Configure password encryption for this router
GATEWAY(config)#service password-encryption
5. Configure the console access
Console access is protected by the 'cisco' password and login is required at console access.
The exec-timeout command automatically logs off user from console after defined inactivity period (2'45'' in this lab)
GATEWAY(config)#line console 0
GATEWAY(config-line)#password cisco
GATEWAY(config-line)#login
GATEWAY(config-line)#logging synchronous
GATEWAY(config-line)#exec-timeout 2 45
GATEWAY(config-line)#history size 10
